Hi writersoul.
I apologize if i did not state my reason clearly, but I dont want to the greeting to be thought of halachically as an affirmation of what they are doing or believing. This was brought about when I was told by someone who was learning Avoda Zora, that if you pass a church and even want to just compliment the artwork of the building or windows, we are not permitted to do so.
Hi old man.
I am uncomfortable with it. And, equally, I would be uncomfortable with wishing someone a happy Ramadan, but I have no plans to move to Israel because of this greeting issue. lol. By the way, are you a Neil Young fan?
